FILE HOLDER.

Application file i November 2?, 1925. Serial No. 71,660.

means whereby the file may be flexed out wardly or inwardly for use ona'concaved or convexed surface, thereby allowing the maximum cuttingefliciency and the file to conform-to the curvature of the surface-beingfiled. r

A further object is to provide a' flexible file holding frame comprisinga U -'shaped member having handle members, andto arms of which U-shapedmember is pivotally connected, preferably loosely, the-fiends of aflexible bar, to which is detachably 'con-= nected a flexible file, andtoprovide an ,adjusting' screw carried, by the] frame and co operatingwith theflexible barand forming means whereby the bar may be flexedoutwardly or inwardly and held in adjusted po sitions. I i

A further object is to provide the upper side of the flexible bar withan apertured plate in which'th'e lower end of the adjusting screw ispivotally mounted, thereby allowing free movement of the flexible bar,and at the same time allowing rotation of the adjusting screw.

A further object is to provide the ends of the flexiblebar withregistering spaced eyes between which the arms of the frame are disposedand pins extending transversely through the eyes and the arms andloosely mounted in the eyes, thereby allowing freedom of movement of theflexible bar inwardly and outwardly during adjustment thereof.

With the aboveand other objects in View the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed,'it being understood. that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawing Figure 1 is a side elevation of the file holder showingthe file inwardly flexed in dotted lines.

holder.

Figure 3 is a vertical transverse sectional view taken on line 33 ofFlgure 1.

Figure 2 is a top plan view of the file Figure 4 is a verticaltransverse sectional I view taken on line 44 of Figure 1.

Referringto the drawing, the numeral 1 designates a U-shaped frame,-thearms 2 of which extend downwardly and are preferably provided withenlargement-s 3 through which transversely disposed pins 4 extend. Theenlargement 3, at one end of the frame, is provided with an upwardly andrearwardly extendin arm 5 which terminates in a handle member 6, whichis adapted to be grasped by one hand of the operator during themanipulation of the device, and .at which time the other hand of theoperator is preferably placed on the handle member 7 adjacent theforward end of the frame so that the operator can apply pressure on thedevice during a filing operation, par icularly when filing concave andconvex surfaces. \Vhere a concave and convex surface is filed with aconventional form of file, the work is laborious, and to a great degreeinaccurate, and at the same time there is not a smooth cutting by thefile. the above difliculty a flexible bar 8 is provided which may beflexed inwardly or outwardly according to whether a concave or convexsurface is being filed. ;-The ends of the bar 8 are provided with spacedeyes 9, through which the pins at loosely extend.

To obviate 17, therefore it will be seen that the oper ator may adjustvthe bow of the flexible plate 8 by rotating the adjusting screw 14.,

and the loose connection of the pins 4 and eyes 9 will allow saidadjustment. Detachably secured to the under side of the flexible bar 8by means of screws 18 is a flexible file 19, which will flex accordingto the arc towhich the flexible bar 8 is flexed by the adjusting screw14, thereforeit will be seen that the operator may easily and quicklyadjust the files according to the surface being' filed, and by soadjusting a ace . smooth out ona concave or convex sur is obtained. a

From the above it will be seen that a file holder is provided which issimple in construction, the parts reduced to a minimum and the holderconstructed in a manner whereby a file may be easily and quickly flexedinwardly or outwardly and held in flexed position for use on a convex ora concave surface, thereby overcoming the common difficult nowexperienced where a common flat le is used on a convex or concavesurface.

The invention having been set forth what is claimed as new and usefulis:-

1. A file holder comprising a frame, a flexible bar carried by saidframe, a flexible file carriedby said bar, and means for flexing theflexible bar.

2. A file holder comprisng a frame, a flexible bar having its endsloosely connected to the frame, means for flexing said bar, and ineansfor attaching a file to said flexible 3. A file holder comprising aframe, arms carried by said frame, a flexible bar, said flexible barhaving its ends loosely connected to the arms of the frame, meanscarried by the frame and cooperating with the bar for flexing the barand holding the same in flexed position, and means for attaching aflexible file to said flexible bar.

4. A file holder comprising. a frame, arms carried by said frame, aflexible bar, spaced eyes carried=by the ends of the flexible bar, saidarmshaving their ends disposed between said eyes, pins extending throughthe eyes and the arms, said ins being loosely mounted in the eyes, an acjusting screw car ried by the frame and cooperating with the flexiblebar whereby the same may be flexed and held in flexed posit-ion, andmeans for attaching a flexible file to the flexible bar.

5. A file holder comprising a U-shaped frame, arms carried by saidU-shaped frame, a flexible file carrying bar, said flexible barbeingeloosely connected to the arms, means for attaching a flexible fileto the flexible bar, an adjusting screw carried by the frame andpivotally connected to the flexible bar intermediate its ends, and ahandle member carried by one of the arms of the U-shaped frame.

6. A file holder comprising a U-shaped frame, the arms of said U-shapedframe termmatmg 1n enlargements, a flexible bar,-

spaced eyes carried by the flexible bar, said enlargements beingdisposed between the spaced eyes, pins extending through theenlargements and having their ends loosely mounted in the spaced eyes.means for attaching a file to one side of the flexible bar, an adjustingscrew threaded through the U-shaped frame, said adjusting screw beingpivotally connected to the flexible bar, one of said enlargementsterminating in a handle member.

In testimony whereof I aifix my signature.
